You need to carefully consider many different things before you can successfully execute the building of a sterilized area or unit. For example, you need to think about the location, the cost, the manufacturing process and the permitted particle saturation as well. The building of such a sterilized unit needs careful coordination between many different departments during the building process. Here are some things that you need to think about when creating a sterilized unit.

What Are They Used For?

Building certain products like medical devices and manufacturing pharmaceuticals will need to be done in a sealed and sterile setup so that contamination can be avoided. The Federal Standards 209E defines this sterilized unit as an area in which the saturation of airborne particles is controlled within a given range.

The Architecture of the Unit

The sterilized units have to be built in such a way that they are able to achieve and maintain a consistent airflow in which the entire body of air within that unit will always be moving in a specific velocity with flow lines that are parallel. This is known as the laminar flow of air. The more the airflow is restricted, the more turbulence there will be. If there is such a turbulence there can be particle movements which will not be right for a sterilized unit. Therefore it’s always better to get the help of cleanrooms Australia builders so that they know exactly how the project needs to be executed.

Measurement and Composition

There are many important measurements that need to be done when constructing a sterilized unit and some of the most important calculations among these would be particle count, the velocity and the air flow, the temperature, surface cleanliness and the humidity within the area. Managers of these units have the right methods to calculate these standards inside the sterilized units and keep them at a constant at all times.

ESD or Electrostatic Discharge

An electric charge will be created when two surfaces rub against each other. Therefore we can say that moving air creates an electrical charge. When people inside a sterilized unit touches various surfaces or walks across the room, it can create an electrical charge. In the case of such an occurrence, you will need to use ESD protective materials that ensure that there will be no damage from an electrical charge. Therefore the managers should know how to prevent ESD and if they do occur, how to control them as best as possible.

Ventilation in the Unit

The ventilation or the makeup air in the sterilized unit is decided by the amount that is needed to maintain a consistent indoor quality of air and to replace the process exhaust as well as for building pressure. The pressure inside a sterilized unit should always be maintained at a static pressure that is higher to the atmospheric pressure in order to avoid any wind infiltration. The only exception would be when you are using a typically hazardous material or in cases where government agencies would require the unit to be at a negative pressure level.
